Microchip PIC12F683.

Map (am40x, some stitching artifacts)

Package

Metal 3

Size is approximately 2020 x 2240 μm (4.52 mm2)

Mask rev marks

EEPROM

SRAM

Flash

Fuses

FIXME

Metal 2

Need to take an overview pic

EEPROM

SRAM

Flash

Fuses

Metal 1

Overetched, need to decap another chip to see

Poly

EEPROM

SRAM

6T cell size is 5.25 μm x 7.35 μm (38.6 μm^2).

Flash

Fuses

Random logic

Random notes

Flash

24 + 32 horizontal = 56 on bottom x 32 on side = 1792 unit cells
Actual flash capacity is 2048 14-bit words = 28672 bits so each unit cell = 16 bits. 4x4?

SRAM

4 columns of 8 bits each
32 rows
Horizontal WLs
Vertical BLs

5 bit row address bus
2 bit col address bus

EEPROM

256 bytes
16 horizontal x 16 vertical = 256 unit cells
Seems to be some dummy bits?
